I have a family member with no cavities despite loving sweets. His dentist told he has extra thick enamel.

I wasn't that lucky and pure oral hygiene standards in eastern Europe didn't help as well. Had half teeth with fillings by age of 20. However, after eliminating sugars, no new cavities in unaffected teeth, just had to replace existing fillings and crown in 10 years.
